RN104 Incremental Backup to USB3
My daily backup to USB seems to be taking forever recently, similar amount of data but it's just not finishing in time. I've hovered over the backup whilst it is running and the overview pop-up says ...
What do I need to use for the destination path if.... the hdd is named USB_HDD_16 and the folder I want to copy to is Digital?
The NAS I'm pushing/copying from has rsync enabled in the settings.
Again, thanks.
- What firmware are you running?
- How is the USB drive formatted?
- How is the backup job set up now?
The best way to do an incremental backup is to use rsync.
Thanks for the reply. Info below...
FW 6.9.5
USB drive formatted to EXT4
Backup is set to daily, local share to usb... it removes contents and then does a full backup
It's now 7hrs in and is transferring at 22.3mb/s... it started mid-morning

Thanks. Personally I'd use NTFS, since I want to be able to access the backup from Windows. But if you have other linux systems, EXT4 is a reasonable choice. If not, I suggest you change to a different format.

I think you must mean MB/s (megabytes, not megabits). This is slow, but it could be a slow drive - particularly if it uses SMR. What model is it?

So that isn't incremental. You can make it incremental by switching to rsync - making the source "remote" and using 127.0.0.1 for it's IP address.
But it is wise to set it up to do a full backup every now and then. I've had USB drives fail on me, and more than once I've found that old files on the drive looked ok, but couldn't be read. Doing the occasional full backup should lower the odds of that.
Thanks again....
We don't access via Windows so always stuck to what was recommended on here many moons ago. Would be happy any format that is quick to be honest.
Yeah, MB/s not mbps.... sloppy typing.
The drive is a Samsung D3 Station
I've tried doing the rsync to 127.0.0.1 but I wasn't able to find the share. Our Nas has 3 shares and I only back 2 of the 3 as one is just for file sharing not storage. Will adding 127.0.0.1 do the entire NAS? Would be good if I can get this working.

Let's start here:
- What would you do if your NAS failed, and you needed the backed up files?
- How would you confirm that your files are actually being backed up?

Well, you do need to enable rsync for the source shares. You don't need to browse for them. There is a guide here: https://kb.netgear.com/29741/How-do-I-back-up-data-between-two-ReadyNAS-OS-6-systems-using-the-backup-manager

127.0.0.1 is a special IP address that is also known as localhost. It's always the local machine. What is backed up depends on the other backup job settings.
If you want to back up the entire NAS, you'd need to configure the backup job with a local source, and make the USB destination remote. So the USB share would need to have rsync enabled (read/write) for that to work. Personally I like one backup job per share myself.

Ok. That model is too small to be SMR.
Still, it doesn't seem to be all that fast. https://www.scan.co.uk/products/4tb-samsung-stshx-d401tdb-d3-station-usb-30-20-external-desktop-hard-drive-carbon-black-for-pc-mac
If you do the math on the two measurements in the above review, you'll get about 25 MB/s on the small file test, and about 57 MB/s on the large file test.
